Transportation Secretary Ray LaHood partnered with the Atlantic Cities blog to answer readers' questions about America's transportation challengers.
The first segment addressed a question that has been on the minds of many passenger train advocates since November's election:
"Given President Obama's intent to build a better national passenger rail system, will there be an increased emphasis on implementing it for the years to come?"
Secretary LaHood provides a brief overview of the 152 planning and construction projects currently in the works, touching on the super-high-speed rail project in California and the higher-speed rail projects taking place in the Midwest.
